HENRY ENDALL, OF SOUTHAMPTON, ENGLAND.

MARINE SIGNALING-LAMP AND THE LIKE.

Specification of Letters Patent.

Patented Sept. 1, 1908.

Application filed August 5, 1907, Serial No. 387,188. Renewed July 27,1908. Serial No. 445,525.

To all whom it may concern:

Be it known that I, HENRY ENDALL, a subject of Edward, King of GreatBritain and Ireland, residing at 55 Arthur road, Southampton, in thecounty of Hants, England, have invented certain new and usefulImprovements in and Relating to Marine Si naling-Lamps and the Like, ofwhich the following is a specification.

The present invention consists of certain improvements in and relatingto marine signaling lamps and the like.

The objects and advantages of these improvements will be clearlyindicated in the following description of the apparatus, which isadapted for producing a flash light according to the Morse or any othersuitable code, more particularly for use upon or in associa tion withships.

A signaling lamp made according to my invention gives much betterresults than any lamp heretofore used for such purpose.

The lamp as well as the mechanism for working same is of exceedinglysimple de sign, and there is little or no liability of its getting outof order.

In order to aid the present description, the accompanying drawings whichillustrate the invention will be referred to, wherein Figure 1 is ageneral front elevation and Fig. 2 a side view of a small detailthereof; Fig. 3 is a side elevation of the lantern with the lensattachment omitted, and Fig. 4 is a central vertical section through thesame including the lens attachment; Fig. 5 is a plan of Fig. 3 withoutthe cover, the interior being shown partly above the level of the lampsand partly below the level of the same; Fig. 6 is an elevation of thelens attachment which was omitted in Fig. 3.

The same reference letters in the several figures denote the same orcorresponding parts of the apparatus.

The lights are inclosed by a pair of cylinders, one fitted into theother, snugly but not tightly, so as to form practically a doublewalledcylinder, the inner one B being so mounted as to be capable of a limitedrotary movement and the other cylinder A being stationary. The cylindersare both provided with slots C, spaced preferably at equal distancesapart around the circumference in the fashion of a grid, so that theslots are open or shut according as the cylinders A and B are relativelyin one position or the other,

but they are normally kept closed. Either cylinder may be rotatable, butin the accompanying drawings the inner one rotates within the outer, thelatter being fixed to a convenient base or support. As the drawingsshow, the inner cylinder B is actuatedin other words, the slots areopenedby an elbow L or other suitable lever operated from the outside,one arm of which enters a recess in the base of the rotatable cylinderand the other arm of which carries a depressing key, or is adapted to beacted upon directly. In the case of a lamp upon a stand ard as in thedrawings, this key may be a lever 12 hinged near to the base of thestandard P and connected to the lever L by a rod Z of suitable length.Nevertheless any other suitable mechanism may be employed to produce thedesired movement.

The lamps D, preferably electric, are carried upon a disk or plate Mwhich is situated at the bottom of the inner (i c. the movable) cylinderB, but is not integral therewith, being immovably fixed upon astationary hollow stem F which is carried down through the mounting O orstandard P and firmly held in place by a screw nut E such stem F formingan axle on which the inner cylinder B can rotate, a ball bearing withballs Q (or a washer or collar) being under the base of such cylinder toreduce friction. This stem F forms a casing for the electric wires whichenter the side of the mount O through an opening G. Surrounding thestationary cylinder A is a revolving lens attachment in the form of acylindrical sleeve R having an opening in one part of it fitted with asuitable lens S hinged thereto on both sides which not only increasesthe range over which the light is visible but provides for a screenwhich protects the operator from the blinding glare of the same andprevents the light from being seen at all points, its rays being thusconcentrated directly on to the object of intercourse, and so keepingthe signal individual and private, and at the same time preventing thesignal light from interfering with other operations being carried out ona ships bridge or in the vicinity of the signaling device. The sleeve Rjust mentioned may rest upon a flange A around the base of the cylinderA which it surrounds and it may be rotated by hand, so as to direct therays toward the desired quarter, but where this part of theapparatus cannot be conveniently worked directly by hand, it may be driven round by apinion acting on a toothed ring and actuated from a shaft in anysuitable manner. The drawings (excepting Figs. 3 and 5) show a simplearrangement in which teeth T are inserted into the lower part of thesleeve R, forming as it were a toothed ring surrounding the lensattachment, adapted to be actuated by an ordinary chain such as apassing over a pair of guide pulleys V (one shown) and eX- tendingvertically to any desired level, where an actuating wheel W suitable forturning by hand is mounted in any convenient manner, such as upon abracket standing out from the standard Ventilation holes H are providedin the base of the fixed cylinder A, and the inner or rotatable one Balso has spaces J to promote ventilation and cooling of the lantern. Acover X provided with ventilating means is fitted upon the stationarycylinder A and its flange may serve to retain the sleeve R in po sition,without however interfering with its rotation,which furthermore is quiteindependent of the rotation of the inner cylinder B already described.After each impulse of the latter by the lever L in one direction, it isreturned to its original position by a spring K, which is strained whenthe lever is actuated and forces the lever back again when the hand ofthe operator is released. Any suitable kind of spring, may, of course,be used. The revolving lens attachment R can, if desired, be made so asto provide an open ing of variable size, such as by adding a slidingshutter as will be well understood. The post or standard P on which thewhole of the lighting apparatus is mounted may be adapted for any heightwhich is convenient and means for raising and lowering may be provided.
